1. A BRCT clamping absorption circuit with short circuit protection, comprising a load module, a short-circuit detection module, a short-circuit protection module, a spike absorption module, a rectifying module, a clamping module and a main control module, wherein,
the load module is connected to a power supply and a load, and is configured to provide a loop for the load;
the short-circuit detection module is connected to the load module for sending a short-circuit signal when the load is short-circuited;
the short-circuit protection module is connected with the short-circuit detection module, and the short-circuit protection module is connected with the load module, and is used for cutting off an output current of the load module when receiving the short-circuit signal of the short-circuit detection module;
the spike absorption module is connected with the load module, the rectifying module is connected with the spike absorption module, and the clamping module is connected with the rectifying module to form a clamping absorption protection for a spike voltage;
the main control module is connected with the short-circuit detection module, and is used for controlling the on-off of a load regulator according to the short-circuit signal.
